A lot of the MU is actually guys who drop their schedule and rebuild it in MU, and take the easy turns and 1/1's when it suits them.
An evening DFW-TUL 1/1 pays the same 10:20 that a morning 3/3 two day does, and leaves the day free, for example.
More doing this thsn just loading up at straight time, and those doing that are probably playing the IMAX game. In that one a pilot pushes their personal MMAX to some near-zero level, and then bids reserve and gets paid for 73/76 hours with no opportunity for the company to use them, or a line and gets paid the bottom of the LCW for whatever little flying they do.
Works great for those who can't hold summer vacation or holidays off, and are willing to bust hump during boring months like February in exchange for a month or sometimes two "off" with pay.
That said, a method of making all flying over the LCW Premium, and awarded accordingly, is probably worth looking at, along with a means to rotate the premium amingst the group.
Anyone wanting to pursue that should be ready to be called unAmerican, socialist, anti-seniority and be ready to persuade a lot of pilots that they should agree to the slaughter of their own personal sacred cattle.
